M-Modules™, ANSI-standardized since 1997, are a mezzanine standard perfectly suited for adding any kind of real-world I/O to the system in a flexible way. They are modular I/O extensions for all types of industrial computers, from embedded systems up to high-end workstations.
The M-Module™ interface - a fast asynchronous parallel interface - offers sophisticated functions like 32-bit data bus, burst transfers up to 100MB/s, DMA and trigger capabilities.
M-Module™ offer direct front-panel connection rather than requiring a separate adapter panel with ribbon-cable connections. This provides a clean path for sensitive signals without loss of data or signal quality - using, for example, shielded D-Sub connectors and COAX cables.
A carrier board in double Eurocard format can accommodate up to four M-Modules™, for instance in a CompactPCI® or VMEbus system.
Typical M-Module™ functionality comprises instrumentation, process I/O, motion, robotics, various general-purpose analog and binary I/O as well as all common fieldbus interfaces.
MEN boards have been developed to work also in rugged environments - qualified or screened regarding shock, vibration, drop, resonance, humidity, chemicals, and up to -40 to +85°C operation temperature.
M-Modules™ have a long-term availability of minimum 10 years (and longer according to individual agreements).
Typical Applications
With a focus on real-world, process I/O, two of the areas where M-Module™ mezzanines are typically used are automation and test and measurement applications.
